The definition of the Law of Attraction could be perhaps more easily explained as the Law of Vibration. Another definition of the Law of Attraction says that with syncronicity, we attract from the outside what you resonate with, on the inside.
Gravity is a fundamental underlying force in the universe. The amount of gravity that something possesses is proportional to its mass and distance between it and another object. This relationship was first published by Sir Issac Newton. His law of universal gravitation says that the force (F) of gravitational attraction between two objects with Mass1 and Mass2 at distance D is: F = G(mass1*mass2)/D squared. (G is the gravitational constant, which has the same value throughout our universe.). Einstein's theory of relativity adds to this.
